[0039] refer to Figure 1 、 Figure 4 、 Figure 5The extrusion module 2 is composed of an extrusion die 21, an extrusion module base plate 22 and an extrusion die clamping plate 23, wherein the extrusion module base plate 22 is made of steel plate, the thickness of the extrusion module base plate 22 is 40 to 80 mm, and circular holes are provided at the corresponding positions of the extrusion module base plate 22 and the lead screw 4. The diameter of the circular hole is the same as the outer diameter of the lead screw 4. A fastening nut 5 is provided on both sides of each circular hole of the extrusion module base plate 22, and the extrusion module base plate 22 is fixed to the lead screw 4 by the fastening nuts 5 on both sides. During use, the extrusion module base plate 22 bears the external force transmitted to the extrusion module 2 during the advancement and unanchoring process. The thickness of the extrusion module base plate 22 can ensure that the extrusion module base plate 22 does not produce obvious deformation during the force process; a countersunk hole matching the outer diameter of the extrusion die 21 is provided in the center of the extrusion module base plate 22. The extrusion die 21 is installed in the countersunk hole, and the extrusion die clamping plate 23 is fixed on the extrusion die base plate 22 by four tension screws 24. The above structure restricts the extrusion die 21 between the extrusion die base plate 22 and the extrusion die clamping plate 23 to ensure that the extrusion die 21 does not move during the advancement and withdrawal of the anchor. Specifically, the extrusion die clamping plate 23 is made of steel plate. The thickness of the extrusion die clamping plate 23 is 15 to 30 mm. A through hole with a diameter between the inner diameter and the outer diameter of the extrusion die 21 is provided in the center of the extrusion die clamping plate 23 to clamp the extrusion die 21 without affecting the passage of the prestressed steel strand. In particular, the inner diameter of the extrusion die 21 changes gradually, and the minimum inner diameter is smaller than the outer diameter of the extrusion anchor 7. In the process of the extrusion anchor 7 passing through the extrusion die 21 under the action of the pushing rod 12, the extrusion anchor 7 shrinks along the diameter direction and engages with the prestressed steel strand 6.

[0040] refer to Figure 1 、 Figure 6 、 Figure 7The anchor withdrawal module 3 is provided with an anchor withdrawal steel pipe 31 that can move toward the extrusion module 2. The anchor withdrawal steel pipe 31 is made of a hollow steel pipe. The inner diameter of the anchor withdrawal steel pipe 31 is 23 to 30 mm. Common specifications of prestressed steel strands with diameters of 15.2, 17.8 and 21.6 mm can all pass through the anchor withdrawal steel pipe 3; specifically, the anchor withdrawal steel pipe 31 is directly fixed on the anchor withdrawal module base plate 32. The fixing method can be welding. The anchor withdrawal module base plate 32 is provided with a through hole with the same diameter as the inner diameter of the anchor withdrawal steel pipe 31 at the corresponding position of the anchor withdrawal steel pipe 31, so that the prestressed steel strand 6 can pass through the anchor withdrawal module 3; the anchor withdrawal module base plate 32 is made of steel plate, and the thickness of the anchor withdrawal module base plate 32 is 40 to 80 mm. The anchor withdrawal module base plate 32 is located at the corresponding position of the guide screw 4. Each of the guide screws 4 is provided with a circular hole, the diameter of which is the same as the outer diameter of the guide screw 4. After the extrusion anchor 7 and the prestressed steel strand 6 are engaged to a predetermined length, the anchor withdrawal module base plate 32 is manually pushed to drive the anchor withdrawal steel pipe 31 to move toward the extrusion module 2. The anchor withdrawal steel pipe 31 hits the extrusion anchor 7 and moves the extrusion anchor 7 toward the hydraulic propulsion module 1 until the extrusion anchor 7 exits the extrusion module 2. Each guide screw 4 is provided with a limiting nut 33 that can prevent the anchor withdrawal steel pipe 31 from hitting the extrusion die 21. The limiting nut 33 is located between the extrusion module base plate 22 and the anchor withdrawal module base plate 32. Before the anchor withdrawal steel pipe 31 hits the extrusion die 21, the limiting nut 33 contacts the anchor withdrawal module base plate 32, thereby preventing the anchor withdrawal steel pipe 31 from hitting the extrusion die 21 and causing damage to the extrusion die 21. This solves the first technical problem mentioned in the background technology. A special anchor withdrawal module is configured, and the anchor withdrawal module moves along the fixed track of the guide screw. Combined with the limiting measures, it can effectively avoid colliding with the extrusion die during the anchor withdrawal operation.

Figures 1 to 7The anchor withdrawal module 3 is hydraulically driven. The anchor withdrawal module 3 is equipped with an anchor withdrawal hydraulic hollow jack 34. The rated output of the anchor withdrawal hydraulic hollow jack 34 is 10 to 40 tons. A threaded through hole matching the anchor withdrawal hydraulic hollow jack 34 is provided in the center of the anchor withdrawal module base plate 32. The surface of the anchor withdrawal hydraulic hollow jack 34 close to the anchor withdrawal module base plate 32 is processed with an external thread. The anchor withdrawal hydraulic hollow jack 34 is installed on the anchor withdrawal module base plate 32 through threaded matching; the inner wall of the oil cylinder of the anchor withdrawal hydraulic hollow jack 34 is reinforced. The work is provided with threads, and the end of the anchor removal steel pipe 31 near the anchor removal hydraulic hollow jack 34 is provided with threads. The anchor removal steel pipe 31 is installed at one end of the anchor removal hydraulic hollow jack 34 near the extrusion module through the threaded connection of the anchor removal steel pipe adapter 35. The anchor removal steel pipe 31 moves toward the extrusion module under the drive of the anchor removal hydraulic hollow jack 34, pushing the extrusion anchor to move toward the hydraulic propulsion module until the extrusion anchor exits the extrusion module. The anchor removal steel pipe 31 is a wearing part. During use, only the anchor removal steel pipe 31 needs to be replaced, thereby reducing the cost of equipment use.

[0042] In actual use, press Figure 1 As shown, the hydraulic propulsion module 1, extrusion module 2, and anchor withdrawal module 3 are assembled in place, allowing them to be used to process extrusion anchors 7 at the ends of prestressed steel strands 6 and to withdraw the anchors. The anchor withdrawal module 3 is removed, and the middle portion of the prestressed steel strand 6 is inserted into the position of the extrusion module 2, allowing them to be used to process extrusion anchors 7 at the middle section of the prestressed steel strand 6. By assembling and disassembling the modules and combining them, extrusion anchors can be simultaneously extruded at both the ends and the middle of the prestressed steel strand, meeting the processing requirements of different application scenarios in actual projects and thereby resolving the third technical problem mentioned in the background technology.

[0043] In summary, in the present invention, the withdrawal of the extrusion anchor is achieved by configuring a special anchor withdrawal module, and combined with limiting measures, it can effectively avoid collision and damage to the extrusion die during the anchor withdrawal operation; a hydraulic hollow jack is used to realize the processing of the extrusion anchor at any position in the middle section of the prestressed steel strand, and the scope of application is expanded; a screw is used to integrate the various functional modules into a whole, and the relative positions of the various functional modules can be continuously adjusted, which is suitable for the connection operations of prestressed steel strands of different diameters and extrusion anchors of different lengths, and has a wide range of applications.
